Maximal operators on spaces BMO and BLO [PDF]

We consider maximal kernel-operators on abstract measure spaces $(X,μ)$ equipped with a ball-basis. We prove that under certain asymptotic condition on the kernels those operators maps boundedly BMO(X) into BLO(X), generalizing the well-known results of Bennett-DeVore-Sharpley and Bennett for the Hardy-Littlewood maximal function.

Weighted estimates for fractional bilinear Hardy operators on variable exponent Morrey–Herz space

Journal of Inequalities and Applications
In this article, we analyze the boundedness for the fractional bilinear Hardy operators on variable exponent weighted Morrey–Herz spaces M K ˙ q , p ( ⋅ ) α ( ⋅ ) , λ ( w ) ${M\dot{K}^{\alpha (\cdot ),\lambda}_{q,p(\cdot)}(w)}$ .

Function spaces between BMO and critical Sobolev spaces

Journal of Functional Analysis, 2006
The function spaces D-k(R-n) are introduced and studied. The definition of these spaces is based on a regularity property for the critical Sobolev spaces W-s,W-p(R-n), where sp = n, obtained by J.Bourgain, H.Brezis, New estimates for the Laplacian, the div-curl, and related Hodge systems, C.

Hybrid Bird Mating Optimizer With Single-Based Algorithms for Combinatorial Optimization Problems

IEEE Access, 2021
Bird mating optimizer (BMO) is a population-based metaheuristic that has been recently extended to solve combinatorial optimization problems. Even though the algorithm shows promising performance in solving combinatorial optimization problems, it suffers

Space of chord-arc curves and BMO/VMO Teichmüller space

Annales Fennici Mathematici, 2022
This paper focuses on the structure of the subspace \(T_c\) of the BMO Teichmüller space \(T_b\) corresponding to chord-arc curves, which contains the VMO Teichmüller space \(T_v\).

On three-dimensional Hall-magnetohydrodynamic equations with partial dissipation

Boundary Value Problems, 2022
In this paper, we address the Hall-MHD equations with partial dissipation. Applying some important inequalities (such as the logarithmic Sobolev inequality using BMO space, bilinear estimates in BMO space, Young’s inequality, cancellation property ...

Bergman projection and BMO in hyperbolic metric: improvement of classical result [PDF]

Mathematische Zeitschrift, 2022
The Bergman projection $$P_\alpha $$ P α , induced by a standard radial weight, is bounded and onto from $$L^\infty $$ L ∞ to the Bloch space $$\mathcal {B}$$ B . However, $$P_\alpha : L^\infty \rightarrow \mathcal {B}$$ P α : L ∞ → B is not a projection.
